Why Some Women Experience Tailbone Pain as the Baby Grows

Your body adjusts to the many changes happening during pregnancy as your baby grows. So, tailbone pain can develop due to the pressure from your growing baby. This condition, also known as coccydynia, becomes more noticeable in the second and third trimesters of pregnancy. You can manage the pain better and feel confident through pregnancy after knowing the reasons for the development of tailbone pain.

Every experience feels new during pregnancy. Some of them are beautiful, but some can be uncomfortable. Tailbone pain can develop in the later stages of pregnancy and may worsen. It can be dull pain, sharp sting or a lot of pressure at the base of your spine while sitting or getting up. You can better manage the discomfort once you know the reasons.

What Exactly Is the Tailbone and Why Does It Hurt in Pregnancy?

Your tailbone, also called the coccyx, is a small bone at the bottom of your spine. It supports your posture and sitting, even though the bone is tiny. Several changes can affect it during pregnancy.
Your uterus expands from about the size of a small pear to the size of a watermelon by the third trimester. This growth shifts your centre of gravity and increases pressure on your lower spine, including the tailbone.

How Does the Growing Baby Put Pressure on Your Tailbone?

Your baby moves lower into your pelvis in the later stages of pregnancy. Thus, the pressure on the bones and ligaments in that area increases. You may experience the following symptoms:

  • A feeling of heaviness in your pelvis
  • Increased discomfort when sitting
  • Pain when changing positions
The pressure on your tailbone feels more if your baby’s position is low or pressing toward your back.

Can Hormones Make Tailbone Pain Worse?

Relaxin is a hormone released during pregnancy, which softens the ligaments and joints to prepare your body for childbirth. Loose joints may lead to instability in your pelvic region. So, your tailbone can get irritated when ligaments around it lose their support, which causes pain. This is common during the second and third trimesters.

Does Weight Gain Affect Tailbone Pain?

Pregnancy leads to about 10–15 kg of weight gain, which can increase the pressure on your spine and pelvic region. This extra weight only adds to the pressure you are already feeling. You will notice the discomfort more if you are carrying twins or have gained weight faster.

What Are Lesser-Known Causes of Tailbone Pain in Pregnancy?

You may also experience pain due to other reasons, apart from pressure, hormones, and weight gain.

1. Previous Tailbone Injury
If you’ve ever fallen on your back or tailbone, that area may be more sensitive.

2. Constipation

Straining in the toilet due to constipation can put extra pressure on the tailbone. It also affects nearly 40% of pregnancy cases.

3. Incorrect Posture
Slouching, leaning back, or sitting for long hours can worsen tailbone pain.

4. Reduced Muscle Strength
Weak pelvic floor or lower back muscles can make your spine work harder.

What Symptoms Should You Watch Out For?

Tailbone pain feels different for everyone, but some common symptoms are very similar.

  • Sharp pain when sitting down
  • Discomfort when standing up from a chair
  • Pain during bowel movements
  • Soreness after long sitting periods
  • A pulling or pressure-like sensation in the pelvis

When Should You See a Doctor?

You should contact your doctor in the following cases:

  • Severe or worsening pain
  • Pain with bleeding or fever
  • Pain affecting your ability to walk or sit
  • Numbness or weakness in your legs

What Can You Do to Ease Tailbone Pain at Home?

There are many ways to reduce the discomfort of your tailbone.

1. Use a Doughnut Cushion

The pressure on the tailbone will feel less if you sit on such cushions

2. Apply Warm Compresses

Heat relaxes stiff muscles and improves blood flow

3. Practice Good Posture

Keep your back straight and avoid leaning backwards

4. Move Frequently

Avoid sitting in one place for too long

5. Try Gentle Exercises

Prenatal stretches, pelvic tilts, and light walking can give relief

6. Strengthen Your Pelvic Floor

Kegel exercises help support your lower back and tailbone

How Can You Prevent Tailbone Pain as Your Baby Grows?

You can reduce the risk of tailbone pain even if you do not have any pain now.

  • Avoid sitting on hard surfaces
  • Maintain a healthy pregnancy weight
  • Wear shoes with good support
  • Sleep on your side with a pillow between your knees
  • Use a firm but comfortable mattress

What to Do Next: A Quick Checklist?

  • Notice when your pain increases
  • Use cushions to reduce pressure
  • Stay active
  • Maintain a good posture while sitting and standing
  • Reach out to your doctor if the pain becomes too much

Emotional and Social Aspects

Tailbone pain can make simple activities, such as sitting at work, travelling, or even resting, feel daunting. It can lead to frustration or stress. But your partner or family can help you with the work so that you do not feel alone.

Sharing responsibilities, taking breaks, and asking for support can improve your comfort and emotional well-being.

Tailbone pain is common during pregnancy and is often due to the growing baby. It shows that your body is changing to support childbirth. But proper care can ease the discomfort. You will also feel comfortable throughout your pregnancy if you seek medical support.
